The balanced chemical reaction is:
$2NaHCO_3\longrightarrow Na_2CO_3+CO_2+H_2O\\\dfrac{n_{NaHCO_3}}{v_{NaHCO3}}=\dfrac{n_{CO_2}}{v_{CO_2}}\\\Rightarrow \dfrac{m_{NaHCO_3}}{2M_{NaHCO_3}}=\dfrac{V_{CO_2}}{\bar{V}}\\\Rightarrow \dfrac{m_{NaHCO_3}}{2\times84}=\dfrac{0.56}{22.4}\\\Rightarrow m_{NaHCO_3}=4.2g$
